No, no, no, no, no. Both are essential. Your facebook page does zip for you in attracting new or one time customers. Your facebook page is for maintaining a customer base and stirring interest.
I’m probably a 6 out of 10 on internet smarts, but I can buy a really nice website template for $60 and customize it to attract customers (please don’t look at my current site, it’s just a temp job until I figure out what I want).
I can tell you there are thousands of people better at it than me who would take a hundred bucks to customize a website template that you would be thrilled with. $200 for a great looking web presence, or $0 for a page that people have to be looking for you specifically?
